Spr& 3 iLg is a vital 
necessity if you want 
GOOD Fruit. It doesn’t 
pay to miss one season, 
even if enemies are not 
visible. Spraying has 
an invigorating effect 
on trees, besides con¬ 
trolling enemies. 
Spraying during the 
dormant period is dis¬ 
tinctly different from 
spraying o n foliage. 
Materials several times 
as strong can be used 
and are needed to con¬ 
trol the scales. 
On account of the life 
Spraying 
habits of enemies, often 
only two to seven days 
are available for any 
one spraying. Do the 
work then, put the ma¬ 
terial on with force and 
cover every inch of 
bark and leaf. 
Get a sprayer that 
is big enough, that will 
give one hundred to 
two hundred and fifty 
pounds of air pressure, 
that is adapted to your 
land and trees, and that 
is durable. Get a power 
outfit, if possible, for 
it does better work than 
a hand pump can. 
three or four applications, 
The Spraying program ordinarily resolves itself into two, 
one while trees are dormant with DENDROL, and the others on blossoms and fruit with 
VERDOL. All applications must be guided by careful study. 
Spraying will pay bigger dividends than anything you can do. Anythng that is worth 
having is certainly worth taking care of. 
BORERS WILL ATTACK FRUIT TREES IN SPITE OF ALL WE CAN DO, and will 
kill many trees if left alone. Trees must be gone over several times each year, and 
should be gone over each April and August. 
DENDROL 
VERDOL 
Dormant Spray Oil 
Dendrol Dormant Spray Oil is a miscible or 
soluble oil which as delivered for use is a trans¬ 
parent oil of clear reddish color. Upon mixture 
with water it forms a milky-white emulsion. 
Dendrol is designed to be used as a dormant 
spray for the control of injurious insects over¬ 
wintering in one stage or another upon shade 
trees, shrubbery and fruit trees. Some of the 
most important of such insects that Dendrol will 
control satisfactorily are San Jose Scale, Oyster 
Shell Scale, Scurfy Scale, Elm Scale, and many 
other scale insects ; also Red Mite, Leaf Rollers, 
Aphids. Pear Pyslla, Case Bearers, and others. 
Dendrol is so made that it forms a uniform 
mixture in the spray tank ; that is, every part 
of the mixture is equal in the proper oil strength 
to every other part. This is very important 
from the standpoint of uniform dependable in¬ 
sect control and safety to the trees. Dendrol 
mixes easily with all kinds of water and can be 
stored for long periods. This makes it easy to 
save money by buying enough for several years. 
Summer Spray Oil 
It is a white creamy substance thicker 
than Dendrol but fluid enough to be poured 
readily. 
It is always uniform in composition and 
quality. 
It will not deterioate or separate in stor¬ 
age and is not easily affected by freezing. 
It mixes readily and completely with all 
kinds of water. 
It is especially effective in the control 
of Codling Moth but will also help in the 
control of Scale, Red Spider, Aphids, Plant 
Bugs and many other injurious insects. 
It combines perfectly with Arsenate of 
Lead, Calcium Arsenate and Zinc Arsen¬ 
ate.
